It is a colored patch (colordiff). Sorry for the mistake. New version attached.

Only if you also have pcscd running.
The patch will impact only people with the following configuration:
- use OpenCT
- use pcsc-lite (file "/var/run/pcscd/pcscd.comm" is present)
- have a CCID reader NOT supported by pcsc-lite but only by OpenCT
In all other cases the patch has no performance impact.
So no impact if you do not use pcsc-lite.
Is that acceptable?
